Abstract (en)
[origin: EP0470618A2] A thermoplastic moulding composition comprising A) from 50 to 95% by weight of polyoxymethylene, B) from 5 to 50% by weight of a rubber-elastic graft copolymer, and optionally conventional additives, where component B) comprises a rubber-elastic core based on at least one polydiene which is at least partially crosslinked, and at least one rigid graft shell, and has a bimodal particle size distribution. Monomers for the formation of the graft shell are styrene, (meth)acrylonitrile and/or methyl methacrylate. The mouldings produced from the moulding compositions have good ductile fracture behaviour, even at low temperatures.
